The video tutorial explains how to solve a linear equation by completing ordered pairs. It demonstrates substituting known values for X or Y to find the corresponding unknown value, ensuring the pair satisfies the equation. The tutorial covers three scenarios: solving for Y when X=0, solving for X when Y=0, and solving for Y when X=-1. It concludes with a graphical verification of the solutions by plotting the points on a graph to confirm they lie on the line represented by the equation.
